Particles.js: ZoomIn loading animation?

[Feeyz]

How is this loading animation made when opening the site or selecting another design?

I was looking for the same thing. It's a simple css animation:

#yourElement canvas {
   animation-name: appear;
    animation-duration: 1.4s;
    animation-fill-mode: forwards;
}

@keyframes appear {
  from {
    transform: scale(0);
    opacity: 0;
  }
  to {
    transform: scale(1);
    opacity: 1;
  }
}
